Practice with real plots

Each challenge starts from a finished ggplot2 chart and asks you to rebuild it as closely as you can.

Run R in your browser

webR powers the coding environment, so you can experiment without installing R or any local packages first.

Contribute a battle

New challenges live in the project repo. Add a self-contained R file and the site can generate the target image.
